Detailed Description

template<class T, unsigned int tp_size>
class SNlowerTriangular< T, tp_size >

Represents a lower triangular matrix (the diagonal can be non zero).

Constructor & Destructor Documentation

(

)

template<class T , unsigned int tp_size>

const SNmatrix< T, tp_size > &

A

)

Construct a lower diagonal matrix from a SNmatrix.

Whatever was over the diagonal is forgotten.

template<class T , unsigned int tp_size>

SNlowerTriangular< T, tp_size >::SNlowerTriangular

(

const SNgeneric< T, tp_size > &

A

)

Construct a lower diagonal matrix from a generic matrix.

Due to the way the data is recorded in SNmatrix and SNlowerTriangular, it could be faster to initialize from a SNmatrix than from a generic one (if you have the choice ...).

template<class T , unsigned int tp_size>

SNlowerTriangular< T, tp_size >::SNlowerTriangular

(

const SNgaussian< T, tp_size > &

A

)

Construct a lower triangular from a gaussian matrix

Member Function Documentation

T & SNlowerTriangular< T, tp_size >::_at ( m_num  l, m_num  c  )

overrideprivatevirtual

Return by reference the content of element (l,c) of the matrix.

If l<c, throws SNnonAllowedChange because _at is destinated to populate the matrix.

Implements SNgeneric< T, tp_size >.
